@veteran68 Thanks for providing that information. Got a kick out of the name. I bought an Apple Macintosh Quadra 950 years ago, about 150 times the pr...

@lee-g Ha, sense indeed. Tell her the virtues of an alternate bottle cap opener personalized with Star Trek logos, or emblem of <insert favorite sp...

@dronebot-workshop Hey Bill, great article and project! I'm kind of the reverse of some here: I liked the idea of a "breakout board" so much I gathere...

@will - Got it, thanks. Number of picoFarads plus some number of zeros. A formula I can remember is much better than an arbitrary lookup. 😎

@Kyosho_Tom - I am definitely a beginner myself, but have found Bill's article and video to be very helpful. I've returned to it several times to remi...

@will @magic-smoke I would second that comment about the Stuarts Project article on GitHub. I've only gone through it once, but it is very well writt...

That's a good idea. I tried it, and think it will work for what I want, not super stiff, but enough to take care of the "wiggle." In fact, I just used...

Hey Andrew, welcome! There's a lot of depth, i.e. a lot you can do with Arduinos. I tend to prefer the Arduino Nano myself, very inexpensive, compact,...
